What generic virtual data rooms miss about maritime transactions.

Virtual data rooms — the secure document repositories used in M&A, real estate, and financial transactions — have been around for decades. They're well-understood tools with a clear value proposition: a secure, permissioned workspace for sharing confidential documents with multiple parties during a transaction.

Maritime professionals have adopted them for S&P and newbuild transactions because the alternative — email attachments and USB sticks — is clearly worse. But "better than email" isn't the same as "fit for purpose." Generic VDRs have structural limitations that show up in maritime transactions in specific, expensive ways.

The document classification problem

In a maritime transaction, the difference between a class certificate with conditions attached and a clean class certificate is commercially significant. A P&I certificate with a named exclusion is different from one without. A survey report covering a specific inspection scope is different from one covering a full condition survey.

Generic VDRs don't know any of this. They store files. They give you a folder structure and a permission model. They don't know what the files contain or what the differences between similar-looking files mean.

This isn't a minor inconvenience. In a 200-document data room with a 48-hour due diligence window, the parties doing the review need to be able to find the right documents quickly, understand what they're looking at, and identify what's missing. A generic VDR requires a human to read every file to know what it is.

The checklist problem

Maritime transactions have standard document requirements that vary by deal phase. The documents needed at MOA signing are different from those needed at closing. The closing set for a flag-change delivery is different from a same-flag delivery. The requirements for a vessel with a class condition differ from a clean vessel.

Generic VDRs have no concept of this. You can build a folder structure that approximates it — but you're doing that work manually, for every deal, with no enforcement mechanism. When something's missing, you find out at closing, not on day one.

The cross-document problem

The most expensive maritime transaction disputes arise from contradictions between documents — not from the content of any single document. The refund guarantee that doesn't match the installment schedule. The delivery date in the MOA that conflicts with the class survey expiry. The MOA clause 11 condition that references a certificate that was never delivered.

These contradictions are visible if you read all the documents carefully and cross-reference them. But reading 200 documents carefully and cross-referencing them is something that takes time — more time than a due diligence window typically allows. Generic VDRs don't help with this at all. They store the documents. Finding the contradictions is still entirely your problem.

The audit trail problem

Post-closing disputes in maritime transactions often hinge on what was disclosed and when — did the seller know about the class condition? Was the survey report showing the structural crack in the data room before DD expired? When a party claims they didn't receive a document, or that a document was added after DD, you need a verifiable record.

Generic VDRs have activity logs. But these are database records that the VDR provider controls. They're not cryptographically signed. They can't be independently verified. In arbitration, "the VDR log says X" is not the same as "here is a tamper-evident record of what happened."

What to use instead

The answer isn't to build a better folder structure in a generic VDR. The answer is a data room built for maritime transactions — one that understands the document types, enforces the checklists, reads across documents for contradictions, and maintains an audit trail that survives closing and holds up in arbitration.

That's what we built Marintel to be.
